Some young Chinese wanting to use the ubiquitous social media app WeChat to keep up with what their parents and grandparents are doing might be in for a surprise – a new study found that 1.35 million elderly users block their family members from viewing their WeChat Moments posts, a feature similar to Facebook’s Timeline.

Tencent released the findings of the survey ahead of Children’s Day, which falls on June 1 in China. The Shenzhen-based internet giant has been criticised by state media for not doing enough to prevent gaming addiction among the young.
